The objectives of the stages are to different, I’d say. But blooming can still happen weeks after you stopped listening to stage 1.
For me it made a major difference that I listened to the full 15 minutes on my third cycle after two cycles of only 3 minute loops.
Saint confirmed that each sub contains 4 stages, each building upon the previous one.
So basically you get the same content 4 times but each time with more depth. So for me, I guess, there was something in the later stages that I needed.
So, I would at least advice, to start low but increase listening time over the 2 cycles, as long as recon doesn’t get to strong.
If you don’t get the results you wanted after 2 cycles and switched to stage 2 nevertheless, blooming could do the rest, or you could decide to come back to stage 1 after tye cycle.
